Purpose: To evaluate the early clinical outcomes of a new diffractive extended\ndepth-of-focus (EDOF) intraocular lens (IOL). Methods: Prospective case series\nenrolling patients undergoing cataract surgery with implantation of the\nEDOF IOL AT LARA (Carl Zeiss Meditec, Jena, Germany). Distance, intermediate\nand near visual acuity were evaluated during a follow-up of 1 month.\nLikewise, defocus curve, binocular mesopic contrast sensitivity, perception of\nphotic phenomena, patient satisfaction and spectacle independence were assessed.\nResults : The study enrolled 38 eyes of 19 patients with a mean age of\n69.5 years. A significant reduction of manifest refraction and improvement in\ncorrected distance visual acuity (CDVA) was observed with surgery (p <\n0.001). All eyes achieved a 1-month postoperative binocular CDVA of 20/20\nor better. Likewise, all eyes achieved a DCIVA of 20/30 or better at 1 month\npostoperatively, and a total of 92.1% achieved DCNVA of 20/40 or better.\nConcerning refractive predictability, 97.4% of eyes had a 1-month postoperative\nspherical equivalent within ±0.50 D. The level of patient satisfaction with\ndistance, intermediate and near vision was high, with 95% of patients reporting\nthat they would have the same surgical procedure with the same IOL\nagain. Difficulties in night driving or associated to halos were low. A total of\n89% of patients reported to be spectacle independent postoperatively. Conclusions:\nThe EDOF IOL AT LARA is able to provide a functional restoration of\nthe visual function across distances after cataract surgery, with very high levels\nof patient satisfaction and minimal incidence of photic phenomena.
